SMON Overview
SMON is Avaya’s standard-setting switch monitoring technology that has now 
been adopted as IETF standard RFC 2613. SMON extends the RMON standard to 
provide the switch monitoring tools and features you need to analyze the switched 
network and all its components.
SMON provides the basis for top-down network monitoring. Top-down monitoring 
starts when the you notice particular traffic flow patterns in a global view of the 
network. The network manager can progressively focus in and find the specific 
source or sources of the traffic.
Using this method, the amount of information the network manager must assess is 
kept to a minimum. Top-down monitoring is robust enough to enable control of 
even the most complex and sophisticated networks.
SMON is an extension of the RMON standard. SMON adds to the monitoring 
capabilities of RMON in the following ways:
It provides additional tools and features for monitoring in the switch 
environment.
It allows monitoring of ATM networks that are based on cells rather than 
packets.
It provides a global view of traffic flow on a network with multiple switches.
SMON monitoring provides:
A global view of traffic for all switches on the network
An overall view of traffic passing through a specific switch
Detailed data of the hosts transmitting packets or cells through a switch
An analysis of traffic passing through each port connected to a switch, and
A view of traffic between various hosts connected to a switch.
SMON extends both RMON I for the MAC layer, and RMON II for the network 
layer and higher. SMON monitoring collects and displays data in real-time.
Top-down view of all traffic:
Network view for selected switches
Network view for selected ports
VLAN  view 
History
L In order to use SMON, you need to enable the SMON feature on the P460 switch 
and use Avaya MSNM with SMON. See "Basic Switch Configuration" in the 
Avaya P460 Installation and Maintenance Guide.
